In article the essence and the maintenance of space activity are considered, its classification, the basic aspects of space activity as много¬уровневой structures is resulted, the legal status of space activity in the Russian Federation reveals. The special attention is given to a role of the space information in modern conditions and the interrelation of space activity and information safety is shown.

In article the estimation of efficiency of the law of management by a corner of folding of sections articulated tracked vehicle which use raises smoothness of a course of the car at the expense of decrease in amplitudes of longitudinal-angular fluctuations section is presented. Application of the given law of management allows to raise average speed of rectilinear movement of the car, with restriction on smoothness of a course, more than on 75 %

This article is dedicated to the description of the process of development of the interaction between the contacting turns of threads in the planetary roller screws. The following cases are investigated: the interaction between roller and screw; and the interaction between roller and nut. The model serves as a basis for all further calculations of the wear resistance of the roller screws, that is a major criterion for their outage. The result was achieved in accordance with the outcome of the high-accuracy measuring of roller screws’ thread shapes and some theoretical development. The derived model permits to account for the intensive tear and wear of the turns of the threading in the details of the roller screws

Method for dynamical systems identification using self-organizing neural networks is considered. Using method VQTAM was constructed self-organizing neural model for blood glucose level of 1-st type diabetic patients. Set of experimental researches for constructed model is performed y is estimated its accuracy

We consider the problem of choosing the rational linear order from the original set of linearly ordered sets. A new approach to solving this problem is proposed. It is based on the representation of the set of linear orders in the form of several partial orders

In article questions of modelling of processes of maintenance of information safety with use of space systems of a various special-purpose designation on the basis of the system approach in astronautics and applications of space methodology are considered. Features of information safety as object of modelling, theoretical and methodological bases of maintenance of information safety, and also possible approaches to modelling of processes in space sphere, in particular, maintenance of information safety with use of space systems reveal.
